如何知道自己手机号码是多少?

如果您使用的是联通手机号码，不知道本机号码可以通过以下方式查询：
1、本机拨打其它带有来电显示手机，查询本机号码。
2、本机拨打当地联通客服热线，转人工查询本机号码。
3、机主本人持有效证件原件到归属地联通自有营业厅查询。

vivo手机可进入手机设置--移动网络/双卡与移动网络--SIM卡信息与设置--移动/联通/电信/广电--SIM卡号码。

部分SIM卡不显示号码，可向朋友拨打电话，确认号码后，自行添加显示。

用手机拨打对方的电话，对方通过来电显示就可得知你的手机号码。拨打客服电话，询问本机号码，则客服会给提示，或者编辑短信本机号码到"10010"或者"10086"

，就会在随后收到的短信中看到本机号码。

还有一个方法，部分SIM在出厂时由运营商写入了手机号码等信息。因此我们直接可以在手机上进行查询。首先进入手机"程序列表"，找到并点击"设置"，然后在设置中找到"关于手机"的字样，在关于手机界面中找到"状态消息"，点击进入，然后就可以查看到本机号码信息。
